| From: | To: |
The Handicap Index (HI) is a measure of a golfer's potential ability based on their best recent scores. It allows players of different skill levels to compete fairly by adjusting their scores according to their handicap.
The calculator uses the UK handicap formula:
Where:
Explanation: The system takes your best 8 score differentials from your most recent 20 rounds, calculates the average, and applies a 0.96 multiplier to determine your official handicap index.
Details: A accurate handicap index is essential for fair competition in golf. It allows players of different abilities to compete on equal terms and tracks improvement over time.
Tips: Enter your score differentials (one per line). You need at least 8 scores to calculate a valid handicap index. Lower score differentials indicate better performance.
Q1: What is a score differential?
A: A score differential is calculated from your gross score adjusted for course rating and slope rating. It represents your performance relative to the course difficulty.
Q2: Why use the best 8 out of 20 scores?
A: This system focuses on your potential ability rather than average performance, ensuring your handicap reflects your best golf.
Q3: What is the purpose of the 0.96 multiplier?
A: The 0.96 multiplier creates a buffer that prevents handicaps from rising too quickly after a few bad rounds while still allowing improvement to be reflected.
Q4: How often should I update my handicap?
A: Handicaps should be updated after every qualifying round to ensure accuracy. Most golf clubs update handicaps weekly.
Q5: What's considered a good handicap index?
A: For men, scratch to 10 is good; 10-20 is average; above 20 is beginner. For women, scratch to 15 is good; 15-25 is average; above 25 is beginner.
